Magalasi Owerengera a Mtundu Wakuda wa LED SF1018

Posankha mafelemu owonetserako, kuwonjezera pa mtengo ndi kukongola monga muyezo, chidwi chapadera chiyenera kuperekedwa ku kukula kwa mawonekedwe osankhidwa ndi mtunda wa interpupillary momwe mungathere, chifukwa zimakhudza mwachindunji khalidwe la kuwala komanso kuvala chitonthozo cha magalasi.Kuzindikiritsa mtundu wa chimango kungaganizire mozama izi: 1. Mafelemu okhala ndi elasticity nthawi zambiri amakhala abwinoko.2. Ubwino wa chimango ndi zokutira zosalala ndi zonyezimira ndi bwino.3. Mafelemu okhala ndi zipangizo zosalala, zazing'ono komanso zofanana ndi zabwino kwambiri.4. Ndi bwino ngati ziwalo zonse zitasonkhanitsidwa mwamphamvu.5. Kukula ndi mawonekedwe a mphete ya galasi ayenera kukhala chimodzimodzi, ndipo mlatho wa mphuno ndi wofanana.Chisamaliro cha Optician 1. Choyamba, muyenera kusankha chipatala cha optical akatswiri kapena chipatala cha maso chokhala ndi mbiri yabwino yokonzekera magalasi a presbyopic.Ubwino ndi ntchito za magalasi zimatsimikiziridwa pamlingo wina.2. Magalasi asanayambe kuikidwa, optometry iyenera kuchitidwa poyamba, ndipo palibe kugula kwakhungu komwe kumaloledwa.Kugula magalasi okonzeka opangidwa ndi presbyopic ayeneranso kudziwa zizindikiro zawo za myopia, ndikuzigula motsogoleredwa ndi akatswiri.3. Magalasi akapangidwa kapena kugulidwa, ogwira ntchito kusukulu adzawafananiza molingana ndi mawonekedwe a nkhope.Nthawi zambiri, ngati magawo ali olondola, mudzamva bwino mukavala magalasi anu atsopano.
